项目摘要

Harnessing the interaction between light and matter is a central topic in quantum optics and emergent quantum technologies. Waveguide-QED (quantum electrodynamics) provides a recent framework in which such interactions, i.e. those between guided photons (particles of light) and elementary quantum emitters (real or artificial atoms), are controlled and engineered through the structure and geometry of the environment in which the two interact. Work under the preceding NSF award has demonstrated the implementation of a novel experimental platform for studies of waveguide-QED effects in the context of ultracold atoms. Here, the wells of an optical lattice (i.e. a crystal made of light) act as quantum emitters, while guided atomic matter waves play the role of light. As a matter-wave analogue of optical waveguide-QED, this platform offers exquisite tunability and control of the relevant parameters along with access to novel geometries, which are difficult to realize otherwise. The project will investigate the interplay of emitter energies, interactions and geometry to study fundamental questions in waveguide-QED, such as how quantum emitters interact with an engineered environment, how they interact with each other, and what novel phenomena can result from the interaction. The project will thereby offer a glimpse at the quantum simulation of exotic material systems, which can guide future technological efforts. The project, which builds on prior NSF-supported work, is devoted to studies of matter-wave analogues of spontaneous-emission phenomena in photonic-crystal waveguides, using arrays of matter-wave quantum emitters in a state-selective optical lattice. The free tunability of both the excitation energy of the emitters and their vacuum coupling in this recently demonstrated platform enables the exploration of a wide range of novel effects across regimes both accessible and inaccessible to standard quantum optical systems. The project aims to investigate Markovian and non-Markovian emission dynamics into one- and higher-dimensional environments that feature multiple spectral gaps and singularities. Furthermore, the project seeks to characterize coherent couplings between emitters mediated by a dynamical bound state via quasiparticle transport and the formation of interacting many-body phases, and to exploit some of the unique features arising from collisional interactions.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

利用光与物质之间的相互作用是量子光学和新兴量子技术的核心主题。波导QED（量子电动力学）提供了一个最新的框架，即这种相互作用，即引导光子（光的颗粒）和基本量子发射器（真实或人工原子）之间的相互作用，通过两者相互作用的环境的结构和几何形状进行控制和设计。根据NSF奖的工作表明，在Ultracold Atoms的背景下，实施了一个新型的波导QED效应的实验平台。在这里，光学晶格的井（即用光制成的晶体）充当量子发射器，而引导的原子质波则起着光的作用。作为光波指导的物质波像类似物，该平台提供了对相关参数的精美可调性和控制，并获得了新的几何形状，这些几何形状很难实现。该项目将研究发射器能量，相互作用和几何形状的相互作用，以研究波导QUD中的基本问题，例如量子发射器如何与工程环境相互作用，它们之间的相互作用以及相互作用会导致哪些新现象。因此，该项目将瞥见外来材料系统的量子模拟，这可以指导未来的技术努力。该项目建立在先前的NSF支持的工作的基础上，用于研究光子晶体波导中自发性发射现象的物质波类似物，并使用状态选择性光学晶格中的Matter-Wave量子发射器阵列。在这个最近展示的平台中，发射器的激发能及其真空耦合的自由调节性使得可以探索在标准量子光学系统中均可访问和无法访问的各种新型效果。该项目旨在将马尔可夫和非马克维亚发射动力学研究成具有多个光谱差距和奇异性的单维环境。此外，该项目试图表征由通过准粒子运输动态结合状态介导的发射器之间的相干耦合以及相互作用的多体阶段的形成，并利用了碰撞互动引起的某些独特特征，这是由NSF的法定任务和众所周知的Intellial Infactiria构成的依据，该奖项反映了构成群体的范围。
